I have replaced the fuel pump and the trottle position sensor and it runs fine sum days other days it shuts off when I try to stop and or spits and spuders to try and stay running and I did a fuel filter to it too. And a tune up it has no codes to go off of it a 5.9 and sum times it smells like gas but if I rev it up real good it runs fine after words. And at iedle it runs rough sum time too or will die.
